H. ‘Rookie Mouse’

Overview

A miniature sport of Hosta 'Holy Mouse Ears' (itself a sport of Hosta 'Blue Mouse Ears'), 'Rookie Mouse' was registered in 2015. This cultivar is distinguished by its very small, nearly round leaves of blue-green with a dull upper surface and glaucous bloom beneath, green slightly rippled margins, and compact mound-like habit.

In the Garden

'Rookie Mouse' reaches approximately 5 inches (13 cm) in diameter and 2 inches (5 cm) in height at maturity, with a moderate growth rate. It performs best in partial to full shade, as is typical for blue-leaved hostas, and is well suited to rock gardens, troughs, or the front of shaded borders. Its miniature size makes it an excellent choice for container culture, where its compact form can be appreciated at close range. Companion plants might include small ferns, miniature sedges, or low-growing shade perennials such as Heuchera or Tiarella.

Care Notes

Provide consistent moisture during the growing season, and apply a balanced, slow-release fertilizer in early spring as new growth emerges. As with most hostas, slug and deer damage is possible; monitor regularly and employ barriers or repellents as needed in typical hosta-growing zones.
